Julie Antenna on QM33120WEVB: What’s the Actual Antenna-to-Antenna Distance?

Wireless Connectivity Ultra-Wideband

Hi everyone,

I’m currently testing PDoA using the QM33120WEVB and QM33110WEVB modules, each connected to an nRF52840-DK board.

The QM33120WEVB is equipped with a Julie antenna(JL359), and I’m curious about the exact physical distance between the antennas when using these modules for ranging.

Does anyone happen to have detailed mechanical specs or reference measurements for the Julie antenna placement on the QM33120WEVB?

Any insights or official documentation references would be greatly appreciated. Thanks in advance!

Hi @jinew,

The exact details about the Jolie antenna are confidential and if you are looking for more details on this, I would recommend to contact your local sales representative to get more information using the “Find your local sales contact” tool here.

In terms of guidelines for AoA designs, we have an application note, APH511, found on our page here which discusses the antenna element spacing in section 3.
